Three experiments were performed to measure thrombus formation on plastic cannulae inserted by cut-down into veins of sheep. On polyethylene tubing, considerable thrombus was present after one day and the amount increased in the subsequent 13 days. When different sized polyethylene tubings were tested, thrombus tended to form in relation to the surface area. Smaller tubings had smaller proportions of their lengths covered with thrombus. There were differences between types of plastics with one batch of polyvinylchloride tubing being virtually non-thrombogenic.
进行了三项实验，以测量通过切开插入绵羊静脉的塑料套管上血栓的形成情况。在聚乙烯管上，一天后就出现了相当多的血栓，并且在随后的13天里血栓量不断增加。当测试不同尺寸的聚乙烯管时，血栓形成的趋势与表面积有关。较小的管子血栓覆盖的长度比例较小。不同类型的塑料之间存在差异，一批聚氯乙烯管几乎不形成血栓。
